JAMES S. EDGINGTON, OF NEAR BELLEFONTAINE, OHIO.

RAILROAD-SPIKE LOCK.

To all whom it may concern:

Be it known that 1, JAMES S. EDGINGTON, a citizen of the United States,residing at near Bellefontaine, in the county of Logan and State ofOhio, have invented a new and useful Improvement in Railroad- SpikeLocks, of which the following is a specification.

Mydevice relates to certain improvements in railway spikeholders and infurnishing a seat for the rail and causing the weight of the rail, theWeight of the train, and the impact of the wheels on the rail all tomore completely hold the spike in place and prevent displacement of therail through the spikes becoming loosened.

Figure 1, is a detached view of my device. Fig. 2, a perspective view ofthe device attached to the rail.

In the drawings A is the railroad tie, B, the rail, O my chair or clampwhich rests between the rail and tie, and overlaps the bottom flange ofthe rail at D. On the other side of the rail my clamp rises verticallyand has a cutaway part or slot E, in the upturned part, and also a holeF, longitudinally through its length and a hole in the bottom of thechair at L, to allow the spike to pass through.

The object of my invention is to prevent the loosening of the spikesthat hold the rails in place, which results from the pounding of therails by the train, when frost or other cause has made the roadbeduneven. It is well known that most railroad accidents result from thespikes becoming loose and the rails spreading.

In operation the clamp O of my device is Specification of LettersPatent.

Application filed January 29, 1912.

v Patented Dec. 31, 1912. Serial No. 674,149.

placed in position under the rail as shown in Fig. 2, the pin F iswithdrawn far enough to allow the staple G to be driven into the tie,the outer point H, being some distance beyond the rail, and the innerpoint I at the edge of the rail and against the same, or through a holein the flange. WVhen the points H and I have been driven home into thetie, so that the connecting part K rests upon the bottom plate of clampO, the pin F is pushed in till its end projects beyond the clamp piece,thus holding the spike securely to the rail, and in the tie.

To spread the rails it would be necessary not only to raise the sameabOVe the tie the length of the spike or staple, but to pull both armsof the staple out of the tie.

The form of clamp shown in Fig. 1, is the preferred type, though theupturned lip D, can be dispensed with, to the more readily allow theclamp to be inserted under the middle of a rail. One or two of theseclamps can he slid endwise on the rails by raising them a little bitwith a crowbar and the lip D, left off the ones in the middle if desiredto more readily slip them under the rail. Or the dirt can be dug awaybetween the ties and the clamp placed and slid along in place.

What I claim is:

The combination with the railroad rail and tie, the plate C, having slotE, in its upturned. portion, of staple G, and bolt F, as and forthepurpose set forth.
